Manufacturer Narrative

Plant investigation: the actual device was returned to the manufacturer for physical evaluation.An exterior visual inspection of the returned cycler showed no signs of physical damage.Upon power up, the cycler touch screen test failed.When powering on the cycler, the ok, stop and up/down arrow push buttons illuminated, however the front panel touch screen remained blank.It was identified that the cause for the blank screen was due to an internal short on transformer (t1) of the inverter board.The inverter board is located on the rear of the touch screen.A known good inverter board was installed and the display became fully operational.An internal visual inspection of the returned cycler encountered no other discrepancies.A device history record review found a prior occurrence of a blank screen.A failure analysis problem report indicated on (b)(6) 2019 that the failure was due to a defective inverter board.Upon completion of the evaluation, the reported issue was confirmed and the cause was determined to be an internal short on the transformer of the inverter board.The cycler was refurbished following the evaluation.
